What is the life of the internal Battery?
1382
The battery life depends on how much you use it and how you treat it. I've had a similar one for 10 years and although I've only used it a couple times per year (more for camping power versus jumping cars), it still holds a charge and delivers well. I've followed the manuals recommendations of "recharge after each use and at least every other month" which I'm sure has helped with that. I saw a review of another unit where someone said "I charged it when I first got it, left it in the car for 10 months, then pulled it out to charge it and it wouldn't recharge". That's what you don't want to do, so always keep it charged if you expect it to deliver. The battery life depends on how much you use it and how you treat it.

You are correct. I've had mine in indoor use for about 2.5 months and show 62% battery remaining.

The unit gets charged when attached to a computer. I assume that the internal battery will permanently fail someday, but mine has been through many recharge cycles while plugged into my computer and it still functions. I guess when mine stops working, away from a computer USB port, I will toss it and buy another.

I have been happy with it. Instead of about 2 hours of unplugged life, the battery gives 3 hours. The physical size is the same.

The battery is internal. I use the power cord in my vehicle, but when I ride with someone else I use the battery. It lasts for well over an hour if you turn on the Screen Saver which turns off the screen. I do not think the battery is replaceable. I have also run it with an external battery designed for cellphones. Same cord.

Hi Isaac, you could expect approximately 3.5 to 4 hours of life from the battery.

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

The internal battery died years ago. Have been using a mini USB phone charger since. Have also powered the device through usb hub. The device lays on my truck dashboard. Device is about 2.5" x 1.5" x .75" going from memory, as I am not at work today. Could be more precise later.

I don't what the life of the battery is, but I have been running my Roomba on it for a couple months now.

It has an internal battery. No need to add your own. Lasts for at least 10 hours between charges.

I haven't done a test (like running movies for hours to clock the battery life), but I would say about 6-7 hours of use. I use it a lot, but only need to charge the battery every 2 days or so. No battery gets used when it's off, either (I know that sounds silly) - for example, I had charged it fully and the. Had it in my bag for 3 days before taking it out to use it, an the battery was still charged to 100%. So far, great battery life. Hope that helps.

I think that I read somewhere that the time which it has on "stand alone" internal battery was about 50 minutes, although I am not sure about that ... I can't find it right now. As far as amperage draw is concerned, I don't have a clue.

I used to get about 12-15 days when new. However, as the battery has gotten older, its life has gone to 8-10 days. And li-ion batteries just die without warning.

It appears that the battery is internal and non-removable. When I received it, I gave it the full 6-8 hour charge and its last over two weeks.

Maybe30 Days, I don't recall. The battery does not hold a charge very well though.

Sorry, I don't really know. I rarely use the battery, except for recently. I took my laptop to a meeting and it lasted 2 hours on an almost full charge. However, the battery was quite drained by that time.
